The Wethepeople Pathfinder Guard Sprocket was born from Felix Prangenburg's desire for a thicker WTP sprocket, with the addition of an equally thick guard keeping your chain protected. That idea was something WTP hadn't done before so they worked with Felix to create the Pathfinder. Built from 8mm thick 6061-T6 alloy that's fully 3D machined making it an incredibly strong and durable sprocket capable of surviving even the most savage of riders. The Pathfinder Sprocket features 9 sprocket bolt holes integrated into the design to prolong life. It includes adapters so you can run the Pathfinder on 19mm, 22mm and 24mm cranks. ###section### Product Specs TYPE: Bolt On MATERIAL: Alloy with Nylon Guard WEIGHT: 123.9g (4.37oz)
